Embora não seja necessário para elementos label com um input aninhado, ainda é uma prática recomendada vincular explicitamente um label com seu elemento input correspondente.

Vincule os elementos label com seus elementos input correspondentes.

--hints--

Você deve dar ao primeiro label um atributo for que corresponda ao id de seu elemento input.

const htmlFor = document.querySelectorAll('ul.answers-list > li > label')?.[0]?.htmlFor;
assert.notEmpty(htmlFor);
assert.equal(htmlFor, document.querySelectorAll('ul.answers-list > li > label > input')?.[0]?.id);

Você deve dar ao segundo label um atributo for que corresponda ao id de seu elemento input.

const htmlFor = document.querySelectorAll('ul.answers-list > li > label')?.[1]?.htmlFor;
assert.notEmpty(htmlFor);
assert.equal(htmlFor, document.querySelectorAll('ul.answers-list > li > label > input')?.[1]?.id);

Você deve dar ao terceiro label um atributo for que corresponda ao id de seu elemento input.

const htmlFor = document.querySelectorAll('ul.answers-list > li > label')?.[2]?.htmlFor;
assert.notEmpty(htmlFor);
assert.equal(htmlFor, document.querySelectorAll('ul.answers-list > li > label > input')?.[2]?.id);

Você deve dar ao label um atributo for que corresponda ao id de seu elemento input.

const htmlFor = document.querySelectorAll('ul.answers-list > li > label')?.[3]?.htmlFor;
assert.notEmpty(htmlFor);
assert.equal(htmlFor, document.querySelectorAll('ul.answers-list > li > label > input')?.[3]?.id);
